This paper presents Ku-band miniaturized circulators based on special ferrite materials developed to enable manufacturing by Low Temperature Cofired Ceramics (LTCC) technology. Since three different materials are co-fired together, special care is taken for these materials to shrink equally during firing. Simulation results give 0.5 dB insertion loss and 14%-20dB bandwidth for the Spinel3800 based circulator including motherboard and SMD transitions.
